Does it make sense to change the theme every other release cycle and

This is a good point - it would be nice to see a somewhat common theme
getting more and more polished with each release. More of an evolution
than a complete redesign each time. That said, the last few themes have
been a bit like this.
Things that are easier to change, like the splash screens and wallpaper
can change more frequently and dramatically. Things that are more
challenging to redesign well, like Gtk and Metacity themes evolve more
slowly.
